NEC-LIST: Re: resonance and Q of an antenna and scattering system

Happy new year, everyone.

    A dicussion of the definition of Q for an antenna is helpful to us. The
conpect of the ratio of energy stored to the energy dissipated per cycle is
according to the definition of the circuit theory. John B. Wood pointed out
that in the case of an antenna, the energy "dissipated" consists of that
dissipated as heat in the antenna structure and radiated into the medium, and
the stored energy is that contained in the reactive near field of the antenna.
The other important problems are what is the definition of resonance of an
antenna or an antenna array, and how to determine the stored energy contained
in the reactive near field of the antennas. Thank you for you kind attention.

    Sincerely

Long Li
